31. Dependence Characteristics of Face Recognition Algorithms
Published: 1/1/2002
Authors: Andrew L Rukhin, Patrick J Grother, P Jonathon Phillips, Stefan D Leigh, E M Newton, Nathanael A Heckert
Abstract: Nonparametric statistics for quantifying dependence between the output rankings of face recognition algorithms are described. Analysis of the archived results of a large face recognition study shows that even the better algorithms exhibit significan ...

32. Transformation, Ranking, and Clustering for Face Recognition Algorithm Performance
Published: 1/1/2002
Authors: Stefan D Leigh, Nathanael A Heckert, Andrew L Rukhin, P Jonathon Phillips, Patrick J Grother, E M Newton, M Moody, K Kniskern, S Heath
Abstract: The performance of face recognition algorithms is recently of increased interest, although to date empirical analyses of algorithms have been limited to rank-based scores such a cumulative match score and receiver operating characteristic. This pape ...

33. A Statistical Test Suite for Random and Pseudorandom Number Generators for Cryptographic Applications
Series: Special Publication (NIST SP)
Report Number: 800-22
Published: 5/15/2001
Authors: Andrew L Rukhin, Juan Soto, James R Nechvatal, Miles E. Smid, Elaine B Barker, Stefan D Leigh, M Levenson, M Vangel, D L. Banks, Nathanael A Heckert, James F Dray Jr, S C. Vo
Abstract: [Superseded by SP 800-22 Revision 1a (April 2010):] This paper discusses some aspects of selecting and testing random and pseudorandom number generators. The outputs of such generat ...

34. Statistical Analysis of Partial Discharge Phenomena - Time of Occurrence Distributions
Published: 10/1/1998
Authors: X. Han, Nathanael A Heckert, James J Filliben, Yicheng Wang
Abstract: This paper presents time-of-occurrence (phase) distributions of individual pulsating partial discharges (PDs) which occur in a point-dielectric gap in air for ac voltage conditions. It is determined that the pulse phase distribution is adequately mo ...
